For the reason of a stable ABI we dont need it, since all of gbm is inside mesa. Maybe it could be used at some point to ease driver loading/sharing or so, dont know, but right now I think its easier to just have this small state tracker. Since its inside mesa we could change it later if it feels better then. >> >> Benjamin Franzke (8): >> dri: Add dupImage to DRIimageExtension >> intel: Implement DRIimageExtension::dupImage >> st/dri: Implement DRIimageExtension::dupImage >> Add gbm (generic/graphics buffer manager) >> gbm: Add dri backend >> gbm: Add gallium (drm) backend >> egl_dri2: Hookup gbm as drm platform >> st/egl: Hookup gbm for drm backend >> >> Makefile | 11 + >> configs/autoconf.in | 10 +- >> configs/default | 14 +- >> configure.ac | 70 ++++ >> include/EGL/eglplatform.h | 6 + >> include/GL/internal/dri_interface.h | 2 + >> src/egl/drivers/dri2/Makefile | 2 + >> src/egl/drivers/dri2/egl_dri2.c | 76 +++-- >> src/egl/drivers/dri2/egl_dri2.h | 11 + >> src/egl/drivers/dri2/platform_drm.c | 99 ++++-- >> src/egl/main/Makefile | 4 + >> src/gallium/state_trackers/dri/drm/dri2.c | 19 + >> src/gallium/state_trackers/egl/Makefile | 3 +- >> src/gallium/state_trackers/egl/common/egl_g3d.c | 18 +- >> src/gallium/state_trackers/egl/common/native.h | 3 + >> src/gallium/state_trackers/egl/drm/modeset.c | 36 ++ >> src/gallium/state_trackers/egl/drm/native_drm.c | 77 ++--- >> src/gallium/state_trackers/egl/drm/native_drm.h | 4 + >> src/gallium/state_trackers/gbm/Makefile | 46 +++ >> src/gallium/state_trackers/gbm/gbm_drm.c | 225 ++++++++++++ >> .../state_trackers/gbm/gbm_gallium_drmint.h | 74 ++++ >> src/gallium/targets/egl/Makefile | 2 +- >> src/gallium/targets/gbm/Makefile | 32 ++ >> src/gallium/targets/gbm/gbm.c | 61 ++++ >> src/gallium/targets/gbm/pipe_loader.c | 192 ++++++++++ >> src/gallium/targets/gbm/pipe_loader.h | 48 +++ >> src/gbm/Makefile | 14 + >> src/gbm/backends/Makefile | 14 + >> src/gbm/backends/Makefile.template | 65 ++++ >> src/gbm/backends/dri/Makefile | 22 ++ >> src/gbm/backends/dri/driver_name.c | 89 +++++ >> src/gbm/backends/dri/gbm_dri.c | 377 >> ++++++++++++++++++++ >> src/gbm/backends/dri/gbm_driint.h | 78 ++++ >> src/gbm/main/Makefile | 90 +++++ >> src/gbm/main/backend.c | 128 +++++++ >> src/gbm/main/backend.h | 36 ++ >> src/gbm/main/common.c | 88 +++++ >> src/gbm/main/common.h | 42 +++ >> src/gbm/main/common_drm.h | 48 +++ >> src/gbm/main/gbm.c | 189 ++++++++++ >> src/gbm/main/gbm.h | 99 +++++ >> src/gbm/main/gbm.pc.in | 12 + >> src/gbm/main/gbmint.h | 81 +++++ >> src/mesa/drivers/dri/intel/intel_screen.c | 27 ++- >> 44 files changed, 2536 insertions(+), 108 deletions(-) >> create mode 100644 src/gallium/state_trackers/gbm/Makefile >> create mode 100644 src/gallium/state_trackers/gbm/gbm_drm.c >> create mode 100644 src/gallium/state_trackers/gbm/gbm_gallium_drmint.h >> create mode 100644 src/gallium/targets/gbm/Makefile >> create mode 100644 src/gallium/targets/gbm/gbm.c >> create mode 100644 src/gallium/targets/gbm/pipe_loader.c >> create mode 100644 src/gallium/targets/gbm/pipe_loader.h >> create mode 100644 src/gbm/Makefile >> create mode 100644 src/gbm/backends/Makefile >> create mode 100644 src/gbm/backends/Makefile.template >> create mode 100644 src/gbm/backends/dri/Makefile >> create mode 100644 src/gbm/backends/dri/driver_name.c >> create mode 100644 src/gbm/backends/dri/gbm_dri.c >> create mode 100644 src/gbm/backends/dri/gbm_driint.h >> create mode 100644 src/gbm/main/Makefile >> create mode 100644 src/gbm/main/backend.c >> create mode 100644 src/gbm/main/backend.h >> create mode 100644 src/gbm/main/common.c >> create mode 100644 src/gbm/main/common.h >> create mode 100644 src/gbm/main/common_drm.h >> create mode 100644 src/gbm/main/gbm.c >> create mode 100644 src/gbm/main/gbm.h >> create mode 100644 src/gbm/main/gbm.pc.in >> create mode 100644 src/gbm/main/gbmint.h >> >> -- >> 1.7.3.4 >> >> _______________________________________________ >> mesa-dev mailing list >> mesa-dev@lists.freedesktop.org >> http://lists.freedesktop.org/mailman/listinfo/mesa-dev >> > > > > -- > o...@lunarg.com > _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
